Bosses or other devices to conm xiiii'iii'd a citiaen of the United States of America, reaidi at Brookggn, Kings county, New Yer ve invent certain new an useful Improvements in Gas-Engines, of which the f owing ia a specification.

My invention relates to gas engines of the class called turbines, and 1t devicea and combinations of devices hereinaftuand claimed. Figure 1 is a side elevation of such en invention. Fig. 2 is sectional view of the lame. Big. is a vertical cross-sectional view onhnel 8 of Fig. 9. Fig. 4 is a tiia a aectiodal view-oi one o the vanes I on Fig. 0 is a vertical longitudinal aectionaf view of the air inlet and compre-ion devices. Fig. 7 is a detail view. of

one of the orated tubes of the carbureter. Fig. is a detail view of the clutch nism inte betweenthe fan carrying 'ahaft of t e'compressing mechanism and the gear wheel which is connected with the actuating power.

The outer casing or cylinder of the en ne is indicated at 1. centric with the outer casing I construct an inner cylinder 8, 4, one part 3- extendmg from hea 2, or a considerable distanoe inward where it abuts a inst a rim of a set of hladee, and the otter Part, 4, j the rim of a succeeding set 0 blades to a )oint in line with the farther end of n 1, where the space between them is cloeetfhy an annular head, a. The space between 1 on the outside and 8 and 4 outhe inside, is intended toconstitute a water jacket for the engine. From the outer face of the annular head 5 another cylinder 6, extends longitudinally outward and is closed by a a central bore and. 7, having to acmmmodate the shaft, and its sleeve,

9. This c liuder 6 is pierced at a number of, places, tore sixteen, and the walls of each suci apcrturc are surrounded by flanges, 10, to the outer edges of which I secure an annular cylinder, 11, the interior face of which is aperture-d to register with the flanged apertures of cylinder 6.

In the heads 2 andt', which are centrally hored for the )urposc, I mount the main shaft, 8, one end carrying a sleeve 9 and the consists in the .7

It haaa head, 2. n-'

stitute suflicient bearings for the slcm ed shaft. are rcfcrahly formed on the heads 2 and'7, buFit such bearings should be insnflicicnt, I could readily extend the shaft and mount it in willow blocks or other suitable supports. lccrc 9 is fitted as closely to the s aft as possible without causing andue friction, and extends from a point some inches without the line of head 7 to a point slightlyv within the line of the head 5 of the main c linder. At the inner cud it carries a circu or disk 18 ri idl secured to it and of a diameter to titc ose y within the cylindcr 4. Ncxtin succession ,to disk 13. surrounding; said sleeve 9 I place a wheel composed o a hub 15, rad an apertnred disk 17 covering its outer face and a partial rim in the form of a flange. 18 extending inward from the edge of disk 17 over the edges of arms 16, to a line just within that of the circle of apertures in cylinder 6. The inner outcr corners of the arms 16 are secured rigidly'to a ring 19,

ial partition arms 16,

trian alarm cross section (as shown in Fig.

rial in that regard, its main purpose being to attach the-partitions disk 17 and rim 18, firnily'to the stationary cylinder and thus hold them also stationary, and, in conjunction with said huh. pal-ti tions and disk, to constitute a Stl'its of chain:- hers to be more particularly described hereafter. Beyond (ink 17 a partition 1t ex.- tcnds from the wall of cylinder 6, inward to a close fit with sleeve 1). It has a series of apertures .22 corresponding in number, size and relative location with the apertures 24 formed in disk 1?. 'Bct-wecn dish 1! and partition 14, I locate a third disk 20, rigidly secured to sleeve 9, so that its movement may he synchronous with that of disk 13, and

so nearly filling the space between 17 and 14' v as to just permit its turning without friction between it and them, and extending ltl, the hub, li i, thc

outward to the innerfate of cylinder 6 and there flanged or connected to a tliingi- 21. which extends inwardly, parallel with thiahaft, lwtween flanged! and the outer fanof ring 10 on the one side and cylinder 3 on the other./to a line beyond the circle of apertures in cylinder 6, and utilistnntiully to head 5.

' plosive mixture from laced and 'ary an arm 82 extendin will comprem the mixture in chamber 53. es Now the ehflft 8 is also started and through the connections already mentioned its motion will be communicated to sleeve 9 and its rigidly attached disks and 13, their motion icing of course always .synchronouta, The motion of disk 20 will speet ily cause it to be in to uncover apertures 22 and 24 and thereby provide free passage for the exc amber 53 intofour evenly spaced Cllfill'lbfll'fi 50. Not only so, but as disk 20 movceon, it. will uncover the four chambers 50, respectively succecdin those first uncovered and thus throughout its motion. When four chambers 50 have thus been filled under pressure,'the further movement of disk 20 will close thecntrance ports and at the samc instant, the movement of.

disk-'13 will begilrtoiopcn ports 23 0f said four. chambers 50, thc'positionsof disk 13 and disk'2O 'ltcing co ad pasted on sleeve 9 as to produce such ctlect: 'hcn apertures 23 are about one-third .open (any'othcr distance may be selected if desired) the circuit closer! 52 reach and make contact between the contacts 51 of the tour chambers 50 already .90 named, s iarks are created at the spark plugs 49 and t 1e charges in those four chambers are tired. The gases produced by the explosions rush through ports 23 into chamber 99 and thence between thec'ntire series of vanes 96- 26, then 29 and then 35 and the pitch of each succeeding set of vanes'bcing reversed, such 7 passage will cause the vanes 29 to rotate in one direction, carrying the-shaft 8 with them,

and the vanes 35 to rotatc in the o iposite direction, carrying sleeve 12 with t em, such power as is developed by such rotation of s eeve 12 being added to the shaft power through gears 47 and 45, pulley '46 and belt 48. 1025 When the explosion ha. taken place and the gas passed out a described, disk 13 again closes ports 23 and in due course the movement of disk 20 brings the apertures in its llange 21 to register with the said four discharged chambers 50 and any remninin gas therein'may escape through the flan ports in cylinder 0 and into and through the annular chamber 11 and out of its exhaust 98, being hastened in that movement by the fresh incomin r explosive mixture which will by that time ie againcnteringthose chambore 50 under pressure. The rcepectivcly Succeeding i'our (:hambcls .lllvarc likewise charged. closed, opened and their charges 120 exploded and delivered into chamber 99and thence to their work as described, and the cycle continues so long as material is furnished and movement permitted. The purpose of chamber 99 is to cll'cct amore evenly continuous movement of the van and therefore the shaft than if the dirt-harm's were directly against the vanes. The gases fill a chamber and in it become a species of butler. From thence they flow agatnat each set of vanes. and not merely the ones opposite the diacharginp chambers. Again the incomin gases ldt to the general pressure in chain r99 which acts as a reservoir from which the power is continually roceeding with a less pulsatory character than would otherwise be the ease. Meanwhile the shaft. 8 has developed motion under the influences named and thenceforth will actuate all f its connected devices, including shaft 6. Its movement of course causes the air forced through pipe 73 to create a pressure on the gaaolene tank and when the pressure in chamber as and tube 54 is momentaril lest ened by the opening of ports 22 and 2 thatpressure already in the gasolene tank acting through the shorter pipe 74 will cause the gssolene enterin below heads 70 to issue in a jet like spray rem holes 72 in tubes 71 and thereb continue to furnish the material needet for the explosive mixture. If shaft 8 should momentarily slow down the action of fans 59 would not necessarily be thereby retarded, for the balance wheel may for that moment proceed at its already acquired speed, clutch 69 being alwa s ready to again seize and turn shaft 56. w ten the speed of shaft 8 again equals that of shaft 50. As they issucfroni between the blades 35, the gases will have acquired a rotary motion of considerable force and might therefore create an objectionable noise if nothing intervened between said blades andexbaust 40. I have therefore introduced the radial plates 37 at this place to guide those gases in the exit and in overcoming the rotary motion muned, obviate the objection the noise might otherwise present. To cool the parts I introduce a stream of water through tube 90. It passes thence to and through space 93 and y centrifugal force 'will tlo out through chamber til and ports 94 an '9" and channels 92 into chamber 07 and ti nce to and out of discharge tube on. tluis furnishing a very convenient means for eii'eeting the desired end; and to enhance the cooling etlect. l sometime-s make so iplementary channels in the thick parta of t tea-anesleading from and to channch ill and it: (as indicated in dotted lines in Fig. 4). 1

As will be manifest. there are times when it is advisable to change the rate of explosion. relative to the revolutions of the shaft and this may herein be rcadilv accoin dished (within the limits set by the location of wheel 80) by rotating screw 86 and thereb lifting or lowering arm 88 and its link which will carry wheel to a lar r or smaller track upon the face of disk 9 and thus decreaseor increase its s as related. I do not limit myself to-t to exact form. proportions or arran meat of tarts herein shown and desert Many oi them'may be changed in various particulars and some may be omitted without departing from the spirit of my invention.
